Osteochondroma is the most common of primary benign bone tumors. It is characterized by protruding mass from metaphysic of long bone with semitranslucent cartilaginous cap on its surface. This lesion, which has its own growth plate, usually stops growing at skeletal maturity. The multiple variant of osteochondroma, namely the osteochondromatosis, may show various deformities around the joints in its course. In addition, sarcomatous change is sometimes developed. One hundred and twenty one patients were diagnosed as osteochondroma or osteochondromatosis from Jan. 1981 to Dec. 1991, and followed-up for 3.4 years(6months-8years). There were 74 cases of solitary osteochondroma(male : female=1.47 : 1), and 47 cases of osteochondromatosis (male : female=1.61:1). The age at initial visit was averaged 19.5 years(2 years 8 months-58 years). In our experience, common sites were distal femur, proximal tibia, proximal humerus in solitary osteochondroma, proximal tibia, distal femur, distal tibia in osteochondromatosis. Mass with or without pain was the most common chief complaint. Familial histories were noted in 38% of osteochondromatosis. The deformity, which needed correction, were found in 10 among 119 cases ; corrective osteotomy in 7 cases, lengthening with Ilizarov apparatus in 3 cases. The complications such as limitation of motion, sensory disturbance, recurrence, persistent deformity after corrective surgery, epiphyseal plate injury, superficial infection, were noted in 28%. During the follow-up period, there were one case of malignant transformation, and recurrence was identified in 7 cases and three of them were reoperated. Interestingly, progressive deformity was noted in 3 cases postoperatively. And, if the tumor produces no symptom and no functional impairment, we recommend minimizing the indication of surgical intervention. In particular, special attention must be taken in growing children in order to avoid inadvertent complications such as progressive deformity.

Until the 1950s, Ascaris was regarded as an essential part of life which controls every aspect of human physiology among Koreans. Therefore, Ascaris should not be removed from human body. Efforts from medical professionals and the Korean government officials who wished to push forward the parasite control program, had to constantly contest with this perception of Ascaris among ordinary Koreans. In 1966, the 'Parasitic Disease Prevention Act' was promulgated and 'the Korean Association for Parasite Eradication (KAPE)' established in Korea. From the 1970s, Korea mobilized 15 million people each year to achieve the eradication goal. Such mass mobilization could not be possible without public awareness on necessity of parasite eradication. Until the early 1960s, however, Korean people were not sympathetic to the needs of eradication of parasites, especially that of Ascaris. Then, what changed the social perception towards Ascaris during the 1960s? What contributing factors allowed the mass mobilization and public involvement for that campaign? Employing newspaper articles and periodicals, this paper analyzes how social perception on Ascariasis changed during the 1960s, when the 'Parasitic Disease Prevention Act' was established. During the 1960s, Ascariasis became a shameful disease for Koreans. A series of events made Ascariasis more visible and shameful to Koreans. First event happened with Korean miners who were dispatched to Germany in 1963. When the miners turned out to have been infected with intestinal parasites, they were prohibited from work at the mines by the authorities in Germany and quarantined for several weeks. This humiliating experience of Korean expatriate people having bodies swarmed with parasites became a national shame to Koreans. The parasite infected bodies of Korean workers were revealed to the World through German newspapers. Second event happened when a child died of intestinal obstruction due to Ascariasis. The doctor retrieved 1,063 Ascaris from the bowel of the 9 year-old girl, and the photo of the 1,063 worms was published in several newspapers. It was a shocking visualization of Ascariasis in Korean society. Through these visualizations of Ascariasis, the Korean society began to perceive Ascariasis as a shame of the nation as well as that of an individual.

The peritoneal equilibration test(PET) is used as a tool for determining the characteristics of the peritoneal membrane. Initial PET is recommended at least 1 month after peritoneal dialysis, but PET after 1 month may be difficult to perform on an out- patients basis. Two standard PETs(D/P4Cr) were per- formed in 60 CAPD patients(DM:non DM=22:38). Initial PETs, within one week after starting CAPD and follow up PETs, at least 3 months after CAPD were performed. The initial PET values were compared with subsequent PET values. Clinical data (age, sex, body surface area, BMI, presence of diabetes mellitus, ascites) and laboratory indices(serum albumin, dialysate creatinine clearance, KT/V, protein catabolic rate) were compared with the results of the PETs. In initial PET result, there was negative correlation between D/P4Cr and serum albumin(r=-0.522, p<0.001 N=60). There was no significant difference between initial and follow up(mean+/-S.D.:8.84+/-5.2months after CAPD) D/P4Cr(0.68+/-0.14 vs 0.68+/-0.13). But with passage of time, delta D/P4Cr and delta serum albumin were also negatively correlated (r=-0.459, p<0.001). According to the linear regression analysis, the factor significantly associated with D/P4Cr was serum albumin(coefficients -0.111). In conclusion, serum albumin level is the most important predictor of the peritoneal membrane transport characteristics, and it seems that the timing of PET does not matter, rather the changes of with time are strongly correlated with the changes of the serum albumin level.

The prevalence of obesity is continuing to increase. Self-perceived body image among women has drawn a lot of attention in Korea due to unhealthy weight control trials. This study was conducted to determine the relationship between self-perceived body image and dietary intakes among Korean women. For the analysis, 1,747 subjects were selected after eliminating those who were likely to have recently altered their diet based on the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data. The subjects were divided into three groups: underweight, normal, and obese groups according to their perception of body image. Daily nutrient intakes, NAR (Nutrient Adequacy Ratio), and food intake frequency were assessed according to age group and body image perception. Only energy intake showed differences among the three body image perception groups across all age groups, but not statistical differences. Analysis of NAR and the order of most frequently consumed food items confirmed these findings. The ratio of underweight women that perceived their body size as normal or overweight was higher with younger age. Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. This study confirmed that nutritional knowledge is important for healthy weight control trials. Nutritional education for healthy dieting should be emphasized among Korean women.

The role of particulate matter (PM) in health problems including cardiovascular diseases (CVD) and pneumonia is becoming increasingly clear. Polycyclic aromatic hydrocarbons, major components of PM, bind to aryl hydrocarbon receptor (AhRs) and promote the expression of CYP1A1 through the AhR pathway in keratinocytes. Activation of AhRs in skin cells is associated with cell differentiation in keratinocytes and inflammation, resulting in dermatological lesions. Oleanolic acid, a natural component of L. lucidum, also has anti-inflammation, anticancer, and antioxidant characteristics. Previously, we found that PM 10, induced the AhR signaling pathway and autophagy process in keratinocytes. Here, we investigated the effects of oleanolic acid on PM 10,-induced skin aging. We observed that oleanolic acid inhibits PM 10,-induced CYP1A1 and decreases the increase of tumor necrosis factor– alpha and interleukin 6 induced by PM 10,. A supernatant derived from keratinocytes cotreated with oleanolic acid and PM 10, inhibited the release of matrix metalloproteinase 1 in dermal fibroblasts. Also, the AhR-mediated autophagy disruption was recovered by oleanolic acid. Thus, oleanolic acid may be a potential treatment for addressing PM 10,-induced skin aging.

Aged people are challenged by serious complications from chronic diseases, such as mood disorder, diabetes, heart disease, and infectious diseases, which are also the most common causes of death in older people. Therefore, elderly care facilities are more important than ever. The most common causes of death in elderly care facilities were reported to be diabetes, cardiovascular disease, and pneumonia. Recently, the coronavirus disease 2019 (COVID-19) pandemic have a great impact on blind spots of safety where aged people were isolated from society. Elderly care facilities were one of the blind spots in the midst of the pandemic, where major casualties were reported from COVID-19 complications because most people had one or two mortality risk factors, such as diabetes or cardiovascular disease. Therefore, medical governance of public health center and hospital, and elderly care facility is becoming important issue of priority. Thus, remote health monitoring service by the Internet of Medical Things (IoMT) sensors is more important than ever. Recently, technological breakthroughs have enabled healthcare professionals to have easy access to patients in medical blind spots through the use of IoT sensors. These sensors can detect medically urgent situations in a timely fashion and make medical decisions for aged people in elderly care facilities. Real-time electrocardiograms and blood sugar monitoring sensors are approved by the medical insurance service. Real-time monitoring services in medical blind spots, such as elderly care facilities, has been suggested. Heart rhythm monitoring could play a role in detecting early cardiovascular disease events and monitoring blood glucose levels in the management of chronic diseases, such as diabetes, in aged people in elderly care facilities. This review presents the potential usefulness of remote monitoring with IoMT sensors in medical blind spots and clinical suggestions for applications.

The skin, the largest organ in the body, undergoes age-related changes influenced by both intrinsic and extrinsic factors. The primary external factor is photoaging which causes hyperpigmentation, uneven skin surface, deep wrinkles, and markedly enlarged capillaries. In the human dermis, it decreases fibroblast function, resulting in a lack of collagen structure and also decreases keratinocyte function, which compromises the strength of the protective barrier. In this study, we found that treatment with γ-aminobutyric acid (GABA) had no toxicity to skin fibroblasts and GABA enhanced their migration ability, which can accelerate skin wound healing. UVB radiation was found to significantly induce the production of matrix metalloproteinase 1 (MMP-1), but treatment with GABA resulted in the inhibition of MMP-1 production. We also investigated the enhancement of filaggrin and aquaporin 3 in keratinocytes after treatment with GABA, showing that GABA can effectively improve skin moisturization. In vivo experiments showed that oral administration of GABA significantly improved skin wrinkles and epidermal thickness. After the intake of GABA, there was a significant decrease observed in the increase of skin thickness measured by calipers and erythema. Additionally, the decrease in skin moisture and elasticity in hairless mice exposed to UVB radiation was also significantly restored. Overall, this study demonstrates the potential of GABA as functional food material for improving skin aging and moisturizing.

Hair growth cycles are mainly regulated by human dermal papilla cells (hDPCs) and human outer root sheath cells (hORSCs).Protecting hDPCs from excessive oxidative stress and hORSCs from glycogen phosphorylase (PYGL) is crucial to maintaining the hair growth phase, anagen. In this study, we developed a new PYGL inhibitor, hydroxytrimethylpyridinyl methylindolecarboxamide (HTPI) and assessed its potential to prevent hair loss. HTPI reduced oxidative damage, preventing cell death and restored decreased level of anagen marker ALP and its related genes induced by hydrogen peroxide in hDPCs. Moreover, HTPI inhibited glycogen degradation and induced cell survival under glucose starvation in hORSCs. In ex-vivo culture, HTPI significantly enhanced hair growth compared to the control with minoxidil showing comparable results. Overall, these findings suggest that HTPI has significant potential as a therapeutic agent for the prevention and treatment of hair loss.
